This code is my answer:
<a href="<?php echo get_author_posts_url( get_the_author_meta('ID'), get_the_author_meta( 'user_nicename' ) ); ?>" class="m-article-author">
<?php
$author_bio_avatar_size = apply_filters( 'tierisch_wohnen_author_bio_avatar_size', 49 );
echo get_avatar( get_the_author_meta( 'user_email' ), $author_bio_avatar_size );
?>
<?php
if (get_the_author_meta('display_name') === 'xxx Team') {
echo"The";
}
else {
echo"From";
}
?>
<span class="m-article-author-name"><?php the_author(); ?></span>
</a>
